Cardiopulmonary resuscitation, treatment, and analysis

A non-transitory computer-readable medium associated with treating a person having cardiac arrest comprising:

• instructions operable upon execution by a processor to receive a first segment of electrocardiogram (ECG) data from the person when the person is undergoing cardiopulmonary resuscitation (CPR);
• a first Convolutional Neural Network-based Encoder-Decoder (CNNED) structure trained with a first combination of shockable arrhythmia events and non-shockable arrhythmia events to reduce artifacts due to the CPR;
• a second CNNED structure cascaded with the first CNNED structure and trained with a second combination of shockable arrhythmia events and non-shockable arrhythmia events wherein a number of the shockable arrhythmia events is greater than a number of non-shockable arrhythmia events in the second combination to further reduce artifacts due to the CPR;
• instructions operable upon execution by the processor to determine a first arrhythmia classification using the first CNNED structure, determine a second arrhythmia classification using the second CNNED structure in response to the first arrhythmia classification indicating a shockable arrhythmia event of the person;
• and
• instructions operable upon execution by the processor to transmit a signal to apply a defibrillation shock to the person in response to the first arrhythmia classification and the second arrhythmia classification indicating a shockable arrhythmia of the person.

An automated external defibrillator comprising:

• a processor;
• a lead associated with the processor, wherein the lead is configured to receive a first segment of electrocardiogram (ECG) data from a person when the person is undergoing cardiopulmonary resuscitation (CPR);
• and
• a non-transitory computer-readable medium comprising machine executable instructions for implementing a method comprising:
• a first Convolutional Neural Network-based Encoder-Decoder (CNNED) structure trained with a first combination of shockable arrhythmia events and non-shockable arrhythmia events to reduce artifacts due to the CPR;
• a second CNNED structure cascaded with the first CNNED structure and trained with a second combination of shockable arrhythmia events and non-shockable arrhythmia events wherein a number of the shockable arrhythmia events is greater than a number of non-shockable arrhythmia events in the second combination to further reduce artifacts due to the CPR;
• a third CNNED structure cascaded with the first CNNED structure and trained with a third combination of shockable arrhythmia events and non-shockable arrhythmia events wherein a number of the shockable arrhythmia events is less than a number of non-shockable arrhythmia events in the third combination to further reduce artifacts due to the CPR;
• first instructions operable upon execution by the processor to (i) determine a first arrhythmia classification using the first CNNED structure, (ii) determine a second arrhythmia classification using the second CNNED structure in response to the first arrhythmia classification indicating a shockable arrhythmia event of the person;
• and (iii) apply a defibrillation shock to the person in response to the first arrhythmia classification and the second arrhythmia classification indicating a shockable arrhythmia of the person;
• second instructions operable upon execution by the processor to (iv) determine the second arrhythmia classification using the third CNNED structure in response to the first arrhythmia classification indicating a non-shockable arrhythmia event of the person;
• and (v) not apply the defibrillation shock to the person in response to the first arrhythmia classification and the second arrhythmia classification indicating a non-shockable arrhythmia of the person;
• third instructions operable upon execution by the processor to receive a second segment of the ECG data from the lead and implement the first instructions and the second instructions using the second segment in response to the first arrhythmia classification and the second arrhythmia classification not being in agreement;
• and
• fourth instructions operable upon execution by the processor to stop the CPR for a selected time period, receive a post-CPR segment of the ECG data, restart the CPR, and implement the first instructions and the second instructions using the post-CPR segment in response to the first arrhythmia classification and the second arrhythmia classification not being in agreement for a selected number of segments of the ECG data;
• a shock application device coupled to the lead and to the processor and configured to apply the defibrillation shock through the lead to the person in response to receiving a signal from the processor to apply the shock;
• and
• a display coupled to the processor and configured to display a first indication that a defibrillation shock will not be applied to the person and a second indication informing that the CPR should be temporarily stopped for a selected period of time to obtain a clean segment of ECG data in response to a signal received from the processor.
